Ships Ahoy - OTTTD

Surprise Attack Games announces the release of OTTTDon the Humble
Store and on Steam
for Windows, OS X, and Linux. The game's full title sums it up well, as OTTTD
stands for Over the Top Tower Defense.
This launch trailer
offers a look, and here's a description:

Like explosions? Love giant,
flying, undead sharks? Then OTTTD is the game for you for you! Alternatively, if
you’d like a strategy game that cleverly blends tower defence & RTS genres for a
tactical challenge across an action-packed campaign then OTTTD will scratch that
itch.

We describe the game as “Spaceballs meets Starship Troopers”. But anyone under
30 has no idea what Spaceballs is (their loss) so we fall back on “It’s an
anything-goes TD game that doesn’t take itself seriously.”
